0.25 moles of CO2 is present in 11 grams of CO2.

Explanation:

A mole represents the number of chemical entities in an element or molecule.

Number of moles of an element or molecule is determined by the formula:

The Number of moles (n) = weight of the atom given  ÷ atomic or molecular weight of the one mole of the element or molecule.

Themolar mass of one mole of carbon dioxide is:

12+ ( 16×2)

= 44 gram/mole

The given weight is 44 grams of carbon dioxide.

Putting the values in the equation,

n= 11 gms÷44 gms/ mole

n   = 0.25 mole

Two species of frog mate in the same pond. One breeds in early summer and one in late summer. This is an example of what kind of
MatroZZZ [7]

Answer:

Pre-zygotic, temporal separation

Explanation:

Reproductive isolation mechanism is of two types:

  • Prezygotic mechanism
  • Postzygotic mechanism

Prezygotic mechanism isolation occurs before fertilization and helpful in preventing formation of fertile offspring.

In frog external fertilization occurs. In the external fertilization, eggs and sperms are released in water and fertilization occur outside the water.

Prezygotic isolating mechanisms may include behavioral isolation, temporal isolation, mechanical isolation, gametic isolation and habitat isolation.

Temporal separation in reproduction is the sexual activity in the same geographical range but in different periods.

Therefore, the given reproductive isolation is pre-zygotic, temporal separation.

A sound wave is traveling at 331 m/s and has a frequency of 126 Hz. What is the wavelength?​
damaskus [11]
<h2>Answer</h2>

2.626984127 m

<h2>Explanation:</h2><h2></h2>

You have to know the equation that relates wavelength, frequency, and velocity (it's like speed but a bit different).

v = f x λ

where:

v = velocity

f = frequency

λ = Wavelength

Rearrange to make λ subject:

λ = v / f

We've been given 331 as the speed, 126 as the frequency. Sub it into the equation:

331 / 126 = 2.626984127 m

When you graph an inequality you used a closed dot or a open dot
Naddik [55]
For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution. For < and >, use an open circle to indicate the number itself is not part of the solution.
